Here's a screen shot of an email that got through GMail's spam filter.  

"We are shutting down some accounts due to congestion in our database system and your account was chosen to be deleted. If you are still interested in using our email service please click reply and fill in the space below for verification purpose." 

It almost looks official, and it came into my Inbox, not the Spam box.  

None of you guys would fall for this, but keep an eye out for friends and relatives.
